Everything you’ve done, ready when they ask.

Prepped listens to your interview or meeting, notices each question and drafts the answer from your resume and code in a small window beside the call, with the key points highlighted.

Merge intervals

Given an array of intervals, merge all overlapping intervals.

I built our search platform from zero to 40 million queries a day. The problems I want next are in ranking quality, and at my company that work sits with another team. Your platform group owns both.

How does search stay fast while the index is being rebuilt?

Searching your project filessrc/search/ranker.ts

Queries read from a precomputed index in cache.ts. A rebuild writes a new copy and swaps it in every 30 seconds, so no query waits on it.

From your project · src/search/cache.ts · ranker.ts

Screenshot attached

Sort by start, then walk once and extend the last interval while the next one overlaps.

intervals.sort((a, b) => a[0] - b[0])
for (const [s, e] of intervals) {
  const last = out.at(-1)
  if (last && s <= last[1]) last[1] = Math.max(last[1], e)
  else out.push([s, e])
}

Time O(n log n), space O(n).

Could you share your screen and walk me through it?

Share the latency dashboard and point to Tuesday, when p99 rose to 900 ms.

On Windows 10 (version 2004 or later) and 11, screen shares, recordings and screenshots leave the overlay out.

How it works

Prepare before. Answer during. Review after.

Before
Give it your material
Add your resume, the job description or your projects, and write your own answers in the question bank. Before the meeting starts, Prepped learns where things are in your projects and finds the facts the meeting is likely to need, each with the file, line or page it comes from.

Key points

The key points, at a glance.

Every answer highlights the few words that carry it. Glance at the highlights and say the answer in your own words.

I chose Kafka (Decision) over a database queue because we needed replay (Reason). We moved 14 services (Scope) in two quarters with zero downtime (Result).

Your material

Everything it answers from is yours.

Answers about the code you wrote

Add a project folder or a GitHub repository. When a question is about your project, Prepped searches its files and answers from what it read, naming the file.

Your calendar, ready to set up

Connect Google or Outlook, and upcoming interviews and meetings arrive with their invitations, ready to set up. A reminder comes before each one starts.

Your answers, rehearsed

Write answers in a structure that works and review them on cards until they are ready. A meeting that expects the question is prepared with your answer.

What is a weakness you are working on?

Limits you set

A daily limit and one per meeting. Prepped stops before it would pass either.

Practice with feedback

Mock interviews from the question bank, with feedback on each answer that quotes what you said.

Resumes on paper

Edit your resume on the page against a job description, then export it to PDF or Word.

In six languages

Prepped and this site are in English, Chinese, Japanese, Korean, Spanish and French, and each meeting has its own answer language.

Privacy

Built to be used with consent.

It asks first. Before your first meeting, Prepped asks you to confirm that the people in your conversations agree to be recorded and transcribed.
Audio is saved only if you choose. Recordings are kept only when you turn on the complete meeting record in Settings → Desktop & audio, and only on your computer, as ordinary files that are not encrypted. The transcript is text you can correct or delete, and deleting a meeting removes everything in it.
You know what is shared. Meeting records and the app’s activity record go to Prepped only while you take part in the user experience program, which the app tells you about first. Taking part is a condition of the private test and your choice after it. It contacts an AI provider only for the AI work you ask for, and Soniox only while it listens with online recognition, within the limits you set.
You see the cost. Every answer records what it cost, next to the limits you set.

What Prepped stores and where

Before you start

Questions

Which meeting apps does Prepped work with?

Any app whose sound plays on your computer, such as Zoom or Google Meet, and calls made through your computer. Prepped listens to the system audio and, when you turn it on, to your microphone. Nothing has to be installed inside the meeting app.

Can other people see the window when I share my screen?

On Windows 10 version 2004 and later, the overlay is excluded from screen capture (the main window too, if you turn that on), and we check this with the capture methods Windows provides and with screen sharing in Edge and Chrome. Meeting apps differ, so share your screen once in yours before you rely on it.

Which languages does it understand?

Conversations in Chinese, English, Japanese, Korean and Cantonese, and in 24 other European languages. The app itself is in six languages, and each meeting has its own answer language.

What does it cost?

You pay for the AI work only. Each request is metered, and the daily and per-meeting limits you set stop it before it goes past them. Setting up a meeting costs nothing.

May I use Prepped in a job interview?

That depends on the employer. Many hiring processes ask candidates not to use outside help during a live interview, and some do not allow recording. Read the instructions you were given and ask when they are unclear. Preparing beforehand and practicing with Prepped are open to anyone.

Where are my meetings stored?

The desktop app keeps your meetings on your computer. With an online account, as in the invited test, it also keeps them in your account on the Prepped service, as a backup and for your other devices; project folders stay on the computer that read them. The web app keeps them in your account on the Prepped service. In both, the text an answer needs is sent to the AI provider of the model you chose, and deleting a meeting removes everything in it.
